It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating ...

It's double-barreled, it uses lasers instead of LEDs, and it's machined from a solid block of 6061 aluminum alloy. Come meet the Lumitwin DL700 flashlight, which belts out two converging beams up to a ...

When the green laser encounters atoms along its path through the crystal, it gives the electrons in those atoms a bit of extra energy. In their high-energy state, those electrons can absorb blue light ...

Scientists have made small red and blue lasers for years, but other colors have been a challenge. Researchers have filled an important technology gap by creating orange, yellow and green lasers tiny ...
